treePlotArea 1.3.1.9000

• fritools back on CRAN.

treePlotArea 1.3.1

• Get rid of importing fritools.
• Fixed typo in docs.

treePlotArea 1.3.0

• We now check that trees include the corner's center in their plot area and otherwise assign a correction factor of 0. Such trees occur when the diameters where not measured at breast height and got corrected. Otherwise, bwi2022de would have complained about them being invalid sample trees.
• Streamlined internal status codes.

treePlotArea 1.2.0

• Exported function check_boundaries(). It looks for invalid boundaries, one of which occurs in the federal database of the 2012 survey.
• select_valid_angle_count_trees() now removes trees with a diameter at breast height greater than zero and a distance of 0, for these tree should not be there. Gerald/grenzkreis gives a warning, but assigns a correction factor >= 1. Probably, these trees get filter out somewhere down the food chain. We assign a correction factor of 0 instead of only issue a warning.

treePlotArea 1.1.0

• We are checking for boundaries that happen to run through a tract's corner. It's not even clear how we would define stand if such a boundary would be valid. Despite that we by default keep and not delete these boundaries since they were dealt with by grenzkreis. So we do that, too. You may get rid of them using get_boundary_polygons(..., clean_data = TRUE) explicitly.
• get_corrections_factors() now adds status codes and info to the output.
• Added testing suite for internal function get_corrections_factor, which is the main work horse in the package (to which get_corrections_factors() is just a wrapper looping over the trees.
• Added verbosity to internal function secant_intersection() to not throw warnings all over the place.
• Added internal function tree_and_boundary() for manually double checking on trees and boundaries. It's not documented but you may use it to check on constellation where you have doubts.
• Added validate_data() to validate data to conform to the standards of the federal database.
• get_corrections_factors() now returns NA instead of stopping on any error.

treePlotArea 1.0.0

• Using internal get_options() the define column names in data frames.
• Refactored the options.
• Added set_options() and get_defaults()
• Added vignette.
• Added grenzkreis sources.
• Exported plot_tree_plot_area().

treePlotArea 0.5.0

• Got rid of stale functions.

treePlotArea 0.4.0

• Many minor data, docs and testing stuff done. Package is now quite well tested, but documentation lacks. And we need to pass column names.

treePlotAreas 0.3.0

• Fixed for including triangles.

treePlotAreas 0.2.0

• Use pentagons instead of triangles for flexed boundaries.

treePlotAreas 0.1.0

• Added a NEWS.md file to track changes to the package.
